I try to explain it as comparable to the difference between a subset
that consists of one element (the "[" function always returns a vector
of the same mode as its argument) and the element itself.
Whether that explanation makes sense depends on how comfortable the
listener is with mathematical abstractions. As they say, "There are 10
types of people in this world: those who understand binary numbers and
those who don't."
